The Research on Solid-State Fermentation Technology of Fuel Ethanol Using in Straw

Abstract:

Based on the introduction of the major problems in solid-state fermentation of straw to produce fuel ethanol and its development direction, this paper systematically discuss the process that currently used.Through analyzing the characteristics of all phases such as pretreatment, hydrolysis and fermentation and so on,we put forward a new kind of process scheme. In this process, we use a mixed method which combined dilute sulfuric acids with steam explosion pretreatment method, after water washing, adopt the method of synchronized saccharification solid-state fermentation,by adding pichia and cellulase enzyme hydrolysis,and we can get ethanol solution at the same time of enzyme hydrolysis. Then through filtered, purified, denatured and so on, at last, we get the fuel ethanol. The equipment that this process requires is simple, and its fermentation have high efficiency high and low energy consumption.
